Summary
This case report details a rare instance of mucinous carcinoma, a type of breast cancer, in a 46-year-old woman. The patient experienced successful treatment with no recurrence observed four years post-surgery.
Area of Science:
- Oncology
- Pathology
- Radiology
Background:
- This report focuses on a rare presentation of breast cancer, specifically mucinous carcinoma.
- The case involves a 46-year-old woman with a long-standing left breast lump that recently enlarged.
Observation:
- Diagnostic imaging including mammography, breast echography, and MRI revealed irregular mass shadows and lesions.
- Needle biopsy and subsequent histopathology confirmed the diagnosis of mucinous carcinoma, stage IIA (T2N0 M0).
- Hormone receptor status was estrogen receptor (ER) positive and progesterone receptor (PgR) positive, with HER2 score 0.
Findings:
- The patient underwent pectoralis muscle preservation mastectomy and sentinel lymph node biopsy.
- Post-operative follow-up of 4 years showed no signs of recurrence or metastasis.
- Histopathology confirmed mucinous carcinoma, a less common subtype of breast cancer.
Implications:
- This case highlights the importance of thorough diagnostic evaluation for persistent breast abnormalities.
- The successful management of this mucinous carcinoma case provides valuable insights for rare breast cancer presentations.
- Further research into multiple-lesion mucinous carcinoma could improve understanding and treatment strategies.
